Answer:
D
Step-by-step explanation:
1. 25 + 3u = 2u
-3u = -3u
25 = -u
-25=u
2. 14x - 8 = 6x
8x - 8 = 0
8x = 8
x=1
3. 8.5 - 3z = -8z
8.5 = -5z
-1.7 = z
4. 9m + 14 = 2m
7m + 14 = 0
7m = -14
m = -2
Pythagoras theorem.... The thing I hate the most..
In a traingle if you know two if its sides ( we say A and B ) you square them and get the third side C .
You didn't understand.
Let me explain.
We have a triangle, one side is 4cm other is 3cm how do you find the third side?
Yes, Pythagoras theorem.
That is a^2 + b^2 = c^2.
You square 4 and 3:
That will be 16 and 9 then you add them.
16+9= 25 find the root of 25 that is 5.
You get the third side as 5cm.
That's how you use Pythagoras theorem.
He needs to cut 20
hope this helped all you have to do is multiply 7 1/2 by 2 2/3
Answer: Geometric sequences and exponential functions are very closely related. As a result, geometric sequences and exponential functions look very similar. The fundamental difference between the two concepts is that a geometric sequence is discrete while an exponential function is continuous.
